Family sources tell us ... Bruce and Kanye have never had a "real conversation." As we previously reported, Bruce was not happy when Kim hooked up with Kanye so quickly after she left Kris Humphries.
We're told Kanye is the one who planned every detail of the surprise proposal. We do not know exactly why Bruce was not invited -- whether it was because of Kanye or because of Bruce's separation from Kris.
We do know ... Bruce didn't even know Kanye was popping the question until he got a call from Kim immediately after she got engaged. We're told Bruce was Kim's first call, because Kim considers him to be her father.
